I have several fields in my layers hidden because I don't want my users to see them, but they are totally exposed in the "set filter" action of the Table widget, even the ObjectID field! Why would I ever want the user to be able to filter based on ObjectID? I've tried setting these fields to hidden in Pro before even publishing, in my web map, and in the table widget settings, and none of these settings are respected by the filter function. Am I missing something?
